Three items were carried forward as known gaps rather than quietly dropped. This addresses all three; two are closed outright and one is bounded by an environment limit that is now documented rather than implied. 1. Fuzzing had never actually run (Phase 6 step 6.3). The five cargo-fuzz targets were only compile-checked, so "zero panics on arbitrary input" was an aspiration. They have now been run under nightly libFuzzer: parse_object 1,970,750 runs parse_xref 2,471,345 runs decode_stream 1,120,019 runs parse_content_stream 2,655,663 runs parse_document 2,381,367 runs About 10.6 million executions in total, no crashes and no new findings. That is a real result rather than a green checkmark: the three crashes the corpus found in Phase 6 were the ones worth finding, and the fuzzer confirms the fixes hold under adversarial input. 2. Combo dropdown overlay (Phase 4 step 4.3). A combo box that cannot be opened is a text field with extra steps, so the open list is real state, not a rendering detail. Clicking a combo box opens its options; the dropdown takes a click before any field underneath it, matching the draw order; choosing a row sets the value through DocumentFormEditor; clicking elsewhere dismisses it without changing the value. render_open_combo() returns placement data so the drawing code stays trivial and the geometry is testable without a renderer. 3. Makepad event delivery. Upstream added a makepad_test framework, so this is now testable in principle. Adds a test host binary and six UI tests that drive the widget through the Studio protocol: a real click on the fixture link must surface OpenUri on the host, typing must reach the field, and a click on empty space must emit nothing so the positive assertions are not vacuous. They are #[ignore] by default because the Studio hub cannot start an app in this sandbox: the harness launches with --stdin-loop, which Makepad refuses without a Studio websocket, and the build exits 101 before startup. Upstream own spreadsheet-ui and map UI suites fail identically here with the same error, so this is the environment rather than this code. The tests are checked in and compiled by cargo test so they cannot rot, CI runs them where a hub exists, and the module documents how to run them by hand. Getting there also fixed a real defect in the test host: it copied ui.main_view.render() from the spreadsheet app startup hook, but a plain View has no render method, so the app errored at startup. Validation: TEST_TARGET=pdf ./tools/test-rust-clean.sh (270 tests) TEST_TARGET=pdf-ui ./tools/test-rust-clean.sh (321 tests, 6 ignored) cargo +nightly fuzz run <target> -- -max_total_time=60 (5 targets) Both rustfmt and clippy -D warnings clean.
